新加坡,农场娱乐业

[Sigapore]新加坡是一个农业小国,农业在GDP中所占比例只有约2%,并且大量依靠从马来西亚、中国、印尼和澳大利亚进口食物。然而,这样一个国家,却在今年初宣布击败加拿大,取得2016年联邦农业大会主办权,成为该项国际大会的首个亚洲主办国。它的最新经验是克兰芝田园协会的农场娱乐业模式。     

行为经济学和消费经济行为

本文介绍近年来消费经济理论在美国的一些新的发展，主要介绍了2002年诺贝尔经济学奖得主之一心理学教授卡利门的前景理论。另外也介绍了两个结合心理学和经济学理论研究消费经济行为的实例。本文希望对那些对行为经济学感兴趣的消费经济学家有所启发。

The Appreciation Pressure on RMB Yuan and the Adjustment of RMB Exchange Rate Policy

China has maintained RMB exchange rate nearly unchanged since 1998. However, with the relaxation of capital control, a crawling peg, a more flexible RMB exchange rate regime, is inevitable. Based on improving the current formation mechanism of RMB exchange rate, Chinese government could widen the floating band around the central parity; in the long run, switching the peg from USD alone to a basket of currencies may be a better choice.     

论国际税法及其对国内税收制度的影响

通常认为,国际税法存在国内法规范和国际公法规范两方面的法律渊源.其中,国内法规范主要涉及规范跨境交易的国内税收制度,国际公法规范主要包括税收协定和共识性国际税法.共识性国际税法是以国际税收的机构、文书、解释三者为基础构建的共识性规范.在税基侵蚀和利润转移(BEPS)项目1.0时代,共识性国际税法推动了税收协定和国内相关税收制度的大量修改;迈入BEPS2.0时代,共识性国际税法能否在独立核算原则、独立交易原则和常设机构原则这三项国际税收基石性原则的根本性变革方面发挥作用,有待进一步考察.若BEPS2.0共识可以达成,将强有力地证明共识性国际税法的存在及其重要性.     

The crowding-out effect of elderly support expenditure on household consumption from the perspective of population aging: Evidence from China

The pace of aging in China is accelerating, from the introduction of family planning to the liberalization of the two-child policy, with a growing proportion of families in the 4–2-1 structure. With filial piety in mind, most adult children will live with their elderly parents and share income and expenditure. Concurrently, due to the inadequacy of the social security system, a heavy supplementary burden of supporting the elderly has been placed on adult children. Based on data from the 2011, 2013, 2015, and 2017 Chinese Social Survey (CSS) of the Chinese Academy of Social Sciences (CASS), this study analyzes the objective factors affecting household elderly support expenditure using the ordinary least squares (OLS) estimation method. It also examines the crowding-out effect of elderly support expenditure on the consumption of different types of households through a panel generalized method of moments (GMM) approach. Finally, the crowding-out effect of elderly support expenditure is discussed in a sub-sample according to the number of households needing to support the elderly aged 60 and above. The empirical results illustrate that there is a crowding-out effect of elderly support expenditure on household consumption, and the magnitude of the crowding-out effect varies for diverse consumption. Our study reveals that the crowding-out effect of elderly support expenditure on core consumption is the largest in a sample with different numbers of elderly persons in families. The empirical results for the sub-sample show that the larger the elderly population, the stronger the crowding-out effect of elderly support expenditure on core consumption and the less pronounced the effect on marginal consumption.     

供应链管理环境下军用物资多品种采购的多供应商选择研究

为解决供应链管理环境下军用物资采购多供应商选择问题,建立了以供应综合成本最低为目标函数,满足多个约束条件的组合优化模型。为解决求解的困难,采用变换分解算法,将原模型转换为整数规划问题。根据不同迭代方式,给出了两种基本运算步骤。算例分析表明:该新方法克服了常规供应商选择评价方法只针对单一物资供应过程和面向单一供应商选择过程的局限性。     

Unintended Consequences of Lockdowns: Evidence from Domestic Helpers in Urban China

This paper addresses the reactions of domestic helpers to the Wuhan (Hubei Province) lockdown that began on January 23, 2020. We use a novel dataset containing the information of over 40,000 Chinese domestic helpers registered on a leading professional website from November 2019 to June 2020. The results indicate a declining pattern of short-term labor supply of domestic helpers across 11 major Chinese cities, which shows an increase in the expected monthly wage of domestic helpers in these cities. More importantly, using a difference-in-difference (DID) model, this paper provides some evidence on the existence of labor market discrimination against domestic helpers born in Hubei Province due to employers’ fear of infection.
